Large doses of infrared waves can also damage skin and tissues. Exposure to intense electromagnetic radiation, including infrared radiation, can damage the lens and cornea of the eye. There are no known side effects of using a medical grade IR forehead thermometer. “Infrared thermometers shouldn’t be pointed at … The human eye is sensitive to all of the radiation in the electromagnetic spectrum, especially if that radiation is at very high levels of intensity. This is one of the reasons why people use saunas, but it causes the body to lose its water. And, since the gun is pointed at the forehead to take the temperature, the person claimed it can damage the pineal gland in the brain. Unlike ultraviolet light, which can damage the skin, infrared … No-contact forehead thermometers measure the temperature of the body based on the level of thermal radiation being emitted by the skin. It makes various devices possible and useful, including night vision goggles, lasers, thermographic cameras, communications devices and weather satellites. [citation needed] An infrared thermometer cannot be placed too close to its target, or this proximity causes heat to build up in the thermometer's housing and damages the sensor. People who work near intense radiation must wear goggles. There is an increase in photoaging that leads to wrinkles and fine lines on y… Some health care workers and patients reported sleep disturbances, including … This happens because the skin tends to become loose due to the constant ultraviolet rays. The detector used absorbs the thermal (IR) energy emitted from your forehead and converts that to a electrical potential. The infrared thermometers, however, can be used on the wrist or elbow to measure the body temperature. Some medical experts believe that it is not safe to point the thermometers at the forehead, as its frequent exposure may lead to some health issues. 4 min read. Infrared therapy is a new and innovative light-based method to treat pain and inflammation in various parts of the body. Laser beams are composed of highly amplified electromagnetic radiation (visible light, microwaves, infrared and others). She said: "Last night we made a totally unnecessary trip to the hospital thanks to a pretty expensive/crappy infrared thermometer. Ann Trop Pediatr. The electronic circuit within the thermometer processes the electrical signal to determine the temperature and display the reading on a screen. Non-contact approach may reduce the risk of spreading disease between people being evaluated A recent viral video shows a man speaking about the harmful effect of the infrared thermometer guns, which are being used all over the world to monitor temperature amid the coronavirus outbreak. NASA Earth Observatory: Clouds and Radiation, University of Chicago Press: The First Laser. “A study conducted by MOH Health Technology Assessment Branch, found no scientific evidence on the side effects of taking forehead temperature using infrared thermometers,” he said. 16. These posts have been shared nearly 6,000 times on Facebook since the end of June. The halogen emitter has two drawbacks - its golden light irritates the eyes and it radiates short-wave heat, which has a negative effect on a person. The thermometer tells how hot a person is by measuring the infrared energy coming off the body. There is no noticeable side effect, not from the (optional) red laser dot ( very low power and must defacto be save to your eyes too ) and the real IR reader only reads what infra-red heat you emits, so nothing is radiated towards your body except that little red laser dot. Eye damage The human eye is sensitive to all radiation, including infrared radiation. A Facebook post shared thousands of times claims that taking a person’s temperature with an infrared thermometer near their head risks damaging the pineal gland, which is located in the brain. There is no right way to use it, but pointing it on the forehead is a commonly practised by people all over the world. Infrared radiation has a longer wavelength and lower frequency than visible light. Infrared radiation is invisible but the energy of this region happens to correspond to the approximate level of energy needed to start molecules moving in various ways. Osio CE, Carnelli V. Comparative study of body temperature measured with a non-contact infrared thermometer versus conventional devices. Chennai-based scientist Dr S Rangnathan said there is no such evidence to show that the pineal glands are being damaged because of the infrared thermometer. "Ours was reading 38.1 … On the electromagnetic radiation spectrum, infrared radiation is that which has a frequency lower than red light. IR raises the internal temperature of the eye, virtually “baking” it. The pineal gland is a small endocrine gland in the brain. Sep 9, 2020. Infrared radiation waves are the same as heat waves. “Overexposure to infrared radiation can cause health problems such as skin burns and eye damage, but this is not an issue with infrared thermometers,” Dr Rangnathan added. Too much exposure can damage your eyes and skin. Anything at a temperature above absolute zero has molecules inside of it moving around. The most common kind of contact thermometer uses electronic heat sensors to record body temperature. However, given their unreliability are the risks of damage to the eyes and pineal gland really worth it? The claim is false; experts say infrared radiation in the guns does not harm the brain; health agencies worldwide encourage using thermometer guns to manage the spread of COVID-19, the disease caused by the … Infrared waves are incredibly versatile, but they can also be dangerous. Even your body emits infrared waves of heat, which are detectable by thermal imaging machines. Ng DK, Chan C-H, Lee RS, Leung LC. As much as 65% of the rays can get inside your skin during the treatment, and this can be fatal for your body. Research has shown that, when used correctly, infrared or no-contact thermometers are just as accurate as oral or rectal thermometers. As they move, the molecules emit infrared radiation--a type of electromagnetic radiation below the visible spectrum of light. The infrared radiation can penetrate the human body into the dermis before absorption. The outbreak of COVID-19 has placed the infrared thermometer in the limelight, as a preferred tool for fever detection. Because a laser beam is involved, it is important to be very cautious during its use. Infrared thermometers have produced lower readings in lab tests meant to simulate athletic settings than other devices, which could deprive patients of critical care. The pineal gland also plays an important role in the regulation of female hormone levels and may affect fertility and menstrual cycle. They don’t really need to be brought in contact with the object whose temperature needs to be measured , Laser thermometers can measure temperature from a remote location and it is only necessary that the path of the laser shouldn’t be obstructed .. Laser thermometers advantages. People who work in industries which expose them to infrared radiation for long periods of time may experience eye damage. The tweet contains an image with text claiming that the radiation from temperature guns kills neurons, which the post misspells as ‘neutrons’, and can lead to brain damage. Copyright 2021 Leaf Group Ltd. / Leaf Group Media, All Rights Reserved. Infrared laser thermometers are highly accurate, useful devices that have found applications in many different fields. Infrared thermometer eye damage. The infrared thermometer gun is commonly used in public spaces and offices on people before entering the premises. Though the video claims using it on the wrist is more effect, health experts say the temperature will defer on different body parts. ). The higher the temperature, the faster the molecules move. The same thing happens when you go for infrared heat therapy. It produces melatonin, al serotonin-derived hormone which modulates sleep patterns in both circadian and seasonal cycles. People who work in industries which expose them to infrared radiation for long periods of time may experience eye damage. Prolonged IR exposure can lead cataracts, corneal ulcers, and retinal burns. The detector is passive and does not require an electrical power to it. 3. > 1. Moreover, the red light emitted from the thermometer is for a few seconds and that cannot damage the pineal glands,” he said.
